Abstract
This study presents a comparative assessment of sandcrete hollow blocks and clay bricks as walling materials in residential building construction in Ikorodu, Lagos, Nigeria. A mixed method approach was adopted, incorporating literature review, field observations, and analysis of material performance data obtained from previous experimental studies. In Nigeria, particularly in urban areas such as Lagos State, findings reveal that sandcrete hollow blocks are more widely used due to affordability and ease of production and widespread availability, while clay bricks remain an important traditional construction material known for their superior durability and mechanical strength, thermal performance. The study recommends increased promotion of clay and quality control for sandcrete block production. The study concludes that while sandcrete hollow blocks remain economically attractive for residential construction, their structural reliability depends heavily on proper manufacturing practices and quality control. Improved regulation of block production and increased consideration of clay bricks in suitable construction applications can significantly enhance the long-term performance and sustainability of residential buildings in Lagos State.
